L'Aqueduc de Louveciennes, sometimes called Aqueduc de Marly is an aqueduct built in the 17th century under the reign of Louis XIV, located in Louveciennes. Now out of service, the aqueduct has been listed as a Monument historique since 1953. It was a part of the hydraulic network intended to provide water for the Château de Marly and the Gardens of Versailles from the Seine river, using a huge pump called the Machine de Marly.
The aqueduct consists of 36 arches. Its length is 643m for a width varying from 2 to 4.4m, and a height from 10 to 20 metres.
